Morse code molded into Mars dunes spells out gibberish - CNET

This image is a wonder. NASA's Mars Recoaissance Orbiter snapped it in February while looking down at a series of dark dunes. The shapes of Mars' dunes are usually a clue to wind directions on the planet, but these particular dunes are odd. NASA says "a circular depression (probably an old and infilled impact crater) has limited the amount of sand available for dune formation and influenced local winds. As a result, the dunes here form distinct dots and dashes."

The spacecraft's High Resolution Imaging Science Experiment (HiRISE) camera is responsible for the fascinating photo. The linear dunes are created by winds pushing from two directions at right angles, forcing the sand into long dark stretches. The dots are called "barchanoid dunes," and scientists are still working out what causes their formation on the Red Planet. Crescent-shaped barchanoid dunes can also be found on Earth.

The dots and dashes can be translated into letters using Morse code. Planetary scientist Veronica Bray analyzed the dune image and told Gizmodo the code works out to read "NEE NED ZB 6TNN DEIBEDH SIEFI EBEEE SSIEI ESEE SEEE !!" This may be nonsense, or it might be the crab-people of Mars trying to wa us about the wrath of their ancient gods. Or maybe they're just inviting us to come fishing.
